Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.

(3) Selective heating. Because water molecules absorb microwave best, so high water content part absorb microwave power more than low water content part. This is selective heating characteristics, use this features can be evenly heating and uniform dry;

(4) Drying dehydration direction of water vapor from inside to outside. So microwave drying has expanded role, is a great help to the follow-up of crushing;

(5) Save energy and efficient. Microwave is a direct role in the material, thus no additional heat losses, air inside furnace and corresponding containers won’t heat, then high thermal efficiency, production environment is obviously improved, can save 30% power compared with infra-red radiation.

5,The reason for choosing microwave dryer 1,continue produce, big production 2,keep original color and nutrition 3,easy to control, safety 4,save energy, save cost 5,save labours, only need 1-2 people in all work 6,improve the quality of products, increase income.6, Reference pictureIf you have any questions, please feel free to talk with us.LD Trade is besides you all the time.
